Description
Technical field
The present invention relates to the high pressure superconductive current limiter of a kind of cold and hot medium and container separation thereof.The invention still further relates to the method for designing of described high pressure superconductive current limiter.
Background technology
Along with continuing deeply the research of saturated core type superconductive current limiter, the applicable line voltage distribution grade of superconductive current limiter is also increasing progressively step by step, the capacity of equipment and volume also increase thereupon, and equipment existing structure has also been subject to some restriction, especially superconductive current limiters of extra-high pressure grade.Because its high pressure winding adopts conventional transformer oil insulation, and superconduction winding adopts liquid nitrogen as low-temperature cooling media, for transformer oil and liquid nitrogen two media, temperature when the former normally moves reaches as high as 105 ℃, and the latter's liquid nitrogen temperature is about-196 ℃ (absolute temperature is 77K), both temperature differ larger.As within cooled cryostat is placed in fuel tank, around Dewar, the transformer oil of transformer oil and other position will produce very large temperature gradient on the one hand, this can make the Electric Field Distribution inequality in transformer oil and cause partial discharge, this is except having cooling effect because of transformer oil, also play a part High-Voltage Insulation, and the electric property temperature influence of transformer oil is larger; High temperature transformer oil can make the hull-skin temperature of Dewar raise on the other hand, thereby increases the heat load of Dewar.For saturated core type superconductive current limiter, if structural design, cold and hot medium and container thereof is thoroughly separated, by the important leverage that is the operation of equipment long-term safety.
Application number is that 201010529353.2 patent of invention proposes that a kind of Oiltank structure is realized cold and hot medium and container is separated by changing, but remain following, some is not enough: 1) fuel tank volume is large, complex structure, device assembles difficulty; 2) two lead-in wires that exchange between winding are longer, and need stride across low pressure again to high pressure from high pressure, bring major hidden danger to undoubtedly the safety of High-Voltage Insulation; Although 3, low-temperature (low temperature) vessel Dewar is separated with fuel tank, by fuel tank, surrounded completely, as causing surperficial frosting, vacuum leak is not easy to find early, be unfavorable for the maintenance of Dewar.
Summary of the invention
First technical problem to be solved by this invention, is just to provide the high pressure superconductive current limiter of a kind of cold and hot medium and container separation thereof.
Second technical problem to be solved by this invention, is just to provide a kind of method for designing of above-mentioned high pressure superconductive current limiter.
Adopt the high pressure superconductive current limiter of method for designing design of the present invention, fuel tank volume is little, simple in structure, easily assembling, and the connection lead-in wire having shortened between two high-voltage alternating windings has reduced the potential safety hazard in running, can also make Dewar be placed in and be easy to observe the position of safeguarding, can understand at any time the ruuning situation of cooled cryostat.
Solve above-mentioned first technical problem, the present invention adopts following technical scheme:
The high pressure superconductive current limiter of a kind of cold and hot medium and container separation thereof, comprise the first and second two hollow iron cores (41 that form each phase of superconductive current limiter, 42), square shape iron core two posts are in the vertical direction called and exchange core limb (91, 92), direct current core limb (81, 82), and interchange winding (31), 1 or 2 Dewars that comprise superconduction winding (7) (5), 1 fuel tank (1), it is characterized in that: described interchange winding has 2 (31, 32), being set in two exchanges on core limb, and be arranged in same fuel tank (1), be immersed in transformer oil (2), exchange between winding and be provided with and connect lead-in wire (10), 1 superconduction winding (7) is set with two direct current core limbs simultaneously or 2 superconduction windings (7) are set with two direct current core limbs, is all placed in the Dewar that liquid nitrogen (6) are housed.
On the basis of the above, the present invention can also have various concrete structures:
First, second described interplanar angle theta unshakable in one's determination is 0 °, and two front and back unshakable in one's determination are parallel, and two exchange the same side that core limbs (91,92) are positioned at direct current core limb (81,82);
First, second described interplanar angle theta unshakable in one's determination is greater than 0 ° and be less than 180 °.
Two described iron cores can be made separately also and can be made of one.
Described direct current core limb sectional area is greater than and exchanges core limb sectional area.
Described direct current core limb 81 is greater than respectively with 82 sectional area the sectional area that exchanges core limb 91 and 92, and both are made as n by section ratio; Exchanging core limb 91 equates with the lamination thickness of direct current core limb 81.
The level cross-sectionn of described Dewar (5) is circular.
The two interchange windings that interchange core limb is housed are placed in same fuel tank, can shorten the connecting lead wire between two windings, have reduced insulation safety risk; The superconduction winding that is sleeved on direct current core limb is placed in a low-temperature (low temperature) vessel Dewar, is exposed in air, and two media and container independent operating thereof, do not interfere with each other, and strengthened the security reliability of equipment.
The design of above-mentioned high pressure superconductive current limiter, the situation that is 0 degree to two interplanar angles of iron core is by general method for designing, do are two interplanar angle theta of iron core that special is greater than 0 ° and how to determine the center pillar core section shape that consists of direct current core limb 81 and 82 while being less than 180 °?
Between two iron cores angle theta can be between 0 °～180 ° value flexibly, but be not the simple combination of two iron cores, and will follow certain rule and requirement.For superconductive current limiter, because functional characteristic and superconductor all have certain particularity, unshakable in one's determinationly adopt unequal section design, direct current core limb 81 is greater than respectively with 82 sectional area the sectional area that exchanges core limb 91 and 92, and both are made as n by section ratio.
Simultaneously Dewar 5 is low temperature insulation container made, structurally must do circularly, and superconduction winding 7 in Dewar forms for superconductor coiling.Superconductor is expensive, and in design, the ampere-turn of superconduction winding is certain, and the unique method therefore reducing costs is the circumscribed circle diameter φ that reduces two direct current core limbs 81 and the 82 center pillar iron cores that form; And domestic current making main equipment iron core is laminated structure, for guaranteeing performance unshakable in one's determination, the interchange core limb 91 of superconductive current limiter equates with the lamination thickness of direct current core limb 81.For this kind of structure, difficult point is direct current core limb cross sectional shape how to confirm.
Solve the problems of the technologies described above, the present invention adopts following technical scheme to be:
